Automatic repair of scripts

ABSTRACT

A method and associated system for repairing a running script. A missed object is detected among one or more objects of the running script, the missed object being unrecognized from an original object of a previous running of the script. A change type of the detected missed object is determined. The script is repaired based on the change type.

This application is a continuation application claiming priority to Ser. No. 13/934,278 filed Jul. 3, 2013.

TECHNICAL FIELD

The present invention relates to the script test field, and more specifically, to a method and system for automatic repairs upon script test failure.

BACKGROUND

With the rapid development of computer technology and automation technology, conducting automation tests through scripts is a currently popular test approach. Typically a test object map is always associated with a script in an automation test tool. When a tester catches an object by an object finder, the selected object and its hierarchy (including siblings) can be saved in the test object map. However, since a test cycle of the script is usually long and objects in the script might change in the development phase (for example, since research and development staff members revise the script), some objects cannot be recognized any more (missed). Thus, it happens that testers run scripts for a long time but find that most of them fail because individual objects cannot be recognized any more. The failed object recognition blocks all following steps.

In the prior art, there are three common solutions to the above problem: letting research and development staff members inform testers every time and then revise scripts; upon test failure, making comparison by manually catching using tools such as QTP provided by Hewlett-Packard and the like, so as to learn the reasons for the failure; and manually debugging scripts. Obviously these solutions are laborious and time-consuming, which greatly decreases the test efficiency.

FIG. 1 illustrates a flowchart of a method 100 for automatically repairing a script according to embodiments of the present invention. As shown in FIG. 1, after the method 100 starts, in step S102 a missed object in one or more objects of a running script is determined (i.e., detected) in response to, for example, test failure. The missed object is an object that cannot be recognized any more according to a previous manner in the process of script running. There may be various reasons why an object cannot be recognized. For example, besides the change of the recognition property (among one or more properties of an object, the property for recognizing the object) of an object, the change of the class of an object and the change of the hierarchy of an object in an object hierarchical structure, there is further included a reason that an object itself is not changed, but due to the addition of several objects completely the same as this object, this object cannot be recognized uniquely in a previous way.

Next, the method 100 proceeds to step S104 in which a change type of the missed object is determined. As described above, the change type of an object includes, without limitation, recognition property change, class change, hierarchy change, and no change, for example.

Finally, the method 100 proceeds to step S106 in which the script is automatically repaired based on the change type, such that the script may continue to run without blocking following contents. Then, the method 100 ends.

In order to set forth the present invention more clearly, detailed description is presented below to specific implementations of the respective steps of the method 100 through FIGS. 2-6 in conjunction with a concrete example shown in FIG. 7 according to embodiments of the present invention. It should be noted that the specific implementations being described are merely preferable and not intended to limit the present invention to the scope being claimed. Instead, those skilled in the art may use other equivalent approaches to implementing the above steps of the method 100 without departing from the principle and spirit of the present invention.

FIG. 2 illustrates a flowchart of a method 200 for determining a change type of the missed object according to embodiments of the present invention. According to one embodiment of the present invention, as shown in FIG. 2, after the method 200 starts, it proceeds to step S202 first in which it is determined whether the height of a new hierarchical structure including the missed object changes in comparison with an original hierarchical structure including the missed object. The height of a hierarchical structure is the number of hierarchies, or number hierarchical levels, of the hierarchical structure, since each hierarchy of the hierarchical structure is a hierarchical level of the hierarchical structure. Here, the so-called “original hierarchical structure” and “new hierarchical structure” refer to respective hierarchical structures formed by the missed object and one or more objects in a running script before and after the missed object changes. Those skilled in the art should understand that the “new hierarchical structure” may be obtained according to (such as research and development staffs) changed programs or scripts. For example, respective levels of parent objects and one or more child objects of the missed object are fetched from changed programs or scripts, whereby the “new hierarchical structure” is obtained. By referring to an example 700 shown in FIG. 7, 701 is an object hierarchical structure (i.e., original hierarchical structure) among a plurality of object hierarchical structure in a running script before the script changes. For simplicity purposes, suppose objects (i.e., hierarchies) in this hierarchical structure are a0-a3 from top to bottom of the hierarchical structure, respectively, and their corresponding classes are browser, frame, table and button respectively. Suppose a missed object is a2 (whose class is table), and its possible changes include no change (702), recognition property change (703), class change (704) and hierarchy change (705). Those skilled in the art should understand that this is only a simplified example for clarity purposes, and in actual scripts, the number of objects and the number of corresponding classes may be more than those in the above example.

It should be noted that since in the running script there might be a plurality of hierarchical structures including the missed object, the determining of whether the missed object changes and of its change type may be implemented with respect to each of these hierarchical structures. In addition, in the level of data structure, there are various approaches to implementing the determining of whether the missed object changes and of its change type, which typically include stacks. Of course, those skilled in the art should understand that other data structures may also be used for implementing the determining of whether the missed object changes and of its change type.

The present invention marks (i.e., identifies and records in a storage medium or storage device), the change type of the missed object.

Referring back to FIG. 2, in one embodiment of the present invention, responsive to determining that the height of the new hierarchical structure changes (step S202, Yes), the method 200 proceeds to step S204 in which the change type of the missed object is marked as hierarchy change. With reference to FIG. 7, after determining that the height of the hierarchical structure including a2 changes from originally 4 hierarchies (original hierarchical structure: a0-a1-a2-a3) to 3 hierarchies (new hierarchical structure: a0-a2-a3) (705), the change type of the object table is determined as the hierarchy change.

In one embodiment of the present invention, responsive to determining that the height of the new hierarchical structure does not change (step S202, No), the method 200 proceeds to step S206 in which it is further determined whether an object at the lowest hierarchy in the new hierarchical structure changes or not. Responsive to determining that the object at the lowest hierarchy changes (step S206, Yes), the method 200 proceeds to step S208 in which it is further determined whether the class of the object at the lowest hierarchy changes or not. Responsive to determining that the class of the object at the lowest hierarchy changes (step S208, Yes), the method 200 proceeds to step S210 in which the change type of the missed object is marked as class change. In the example shown in FIG. 7, if the class of the object a2 changes from table to list, then the text object type of this object changes accordingly. At this point, during judging the change type of an object, since the height of the hierarchical structure including a2 is 4 still, it is determined whether an object at the lowest hierarchy in this hierarchical structure changes or not. Since the object at the lowest hierarchy changes from originally a3 to a3′, it is further determined that the class of a3′ changes to text from button of a3. Hence, the change type of the object may be determined as class change.

Still referring to FIG. 2, in one embodiment of the present invention, responsive to determining that the class of the object at the lowest hierarchy does not change (step S208, No), the method 200 proceeds to step S212 in which the change type of the missed object is marked as recognition property change. With reference to 703 in the example of FIG. 7, the initial recognition property of a2 is, for example, its name, and subsequently the name changes to a2′. Hence, when determining the change type of the object, if it is determined that the height of the hierarchical structure including a2 is 4 still and the object a3 at the lowest hierarchy does not change, then the change type of the object a2 may be determined as recognition property change.

With reference to FIG. 2 still, in one embodiment of the present invention, responsive to determining that the object at the lowest hierarchy does not change (step S206, No), the method 200 proceeds to step S214 in which it is determined whether each object changes or not, upwards along the new hierarchical structure starting from a parent object of the object at the lowest hierarchy. Responsive to determining that at least one object changes upwards along the new hierarchical structure (step S214, Yes), the method 200 proceeds to S204 in which the change type of the missed object is marked as hierarchy change. As is clear from the example shown in FIG. 7, another typical case about hierarchy change is as shown in 706, wherein although the height of the hierarchical structure where a2 is located is still 4, actually a2 is not located in the original hierarchical structure, i.e., the hierarchical structure changes. In this case, the method is as below: when determining that the object a3 at the lowest hierarchy does not change, the method traces to each hierarchy of parent object of a3, determining whether it changes or not; when determining that the second hierarchy of parent object of a3 changes from originally a1 to a1′, the change type of the object a2 may be marked as hierarchy change.

Returning to FIG. 2, in the optional embodiment of the present invention, after all parent objects are compared, responsive to determining that none of them changes (step S214, No), the method 200 proceeds to step S216 in which the change type of the missed object is marked as no change. In this case, typically an object itself does not change, whereas one or more other objects having the same recognition property (e.g., the same name) are added, at which point the object cannot be uniquely recognized according to the original recognition property. For example, there are multiple a2 in 702 of FIG. 7. Thus, the method 200 ends.

It should be noted that as described above, since there might be a plurality of hierarchical structures including the missed object, there might be a plurality of change types of the object as returned with respect to the respective hierarchical structures, and a final result being returned is, for example, a statistical value of the plurality of change types. In one embodiment, a change type with the largest statistical value is taken as a final change type. In another embodiment, besides a statistical value, other factors are taken into consideration, such as modification habit of research and development staffs, returned test results and so on, so as to determine a final change type of the missed object.

FIG. 3 illustrates a flowchart of a method 300 for automatically repairing a test script when determining that the change type of an object is no change, according to embodiments of the present invention. As shown in FIG. 3, responsive to determining that the change type of the missed object is no change (S216), a plurality of objects having the same class and recognition property as the missed object are fetched from a plurality of child objects of the parent object of the missed object (step S302). It should be noted that the term “child objects” include direct child objects and/or indirect child objects throughout the present invention. Next, the “perform the same action-compare” process is implemented, that is, causing all objects to perform the same action (step S304) so as to determine whether a following object fetched is the same as a following object that ought to be fetched from causing the missed object to perform the same action before change; determining an object leading to the same following object (step S306, Yes) as the missed object (step S308), and continuing the script running (step S310). According to an optional embodiment of the present invention, when there is no object leading to the same following object (step S306, No), relevant contents of the following object are skipped over by commenting in the script (step S312). A following object fetched by the following object is used as a new following object fetched (step S314), and the step S304 is repeated until the missed object is found. For example, under the type of no change (702) as shown in FIG. 7, a plurality of a2 are caused to perform the same action so as to determine whether a following object fetched is the original a3 or not; if yes, then the a2 is determined as a target a2, and the script running is continued. If an expected a3 will not be fetched after all a2 perform the same action, then a typical reason is that a3 itself has fault. At this point, relevant content of a3 is skipped over (e.g., by commenting out), and a following object of a3 is used as a following object of a2 (not shown in FIG. 7), and a new round of “perform the same action-compare” process is re-implemented in step S304.

FIG. 4 illustrates a flowchart of a method 400 for automatically repairing a test script when determining that the change type of the missed object is recognition property change, according to embodiments of the present invention. As shown in FIG. 4, the method 400 comprises: responsive to determining that the change type of the missed object is recognition property change (S212), the method 400 proceeds to step S402 in which one or more child objects of the parent object of the missed object are fetched (step S402). When among the one or more child objects there is only one unique object having the same class but a different recognition property with the missed object (step S404, Yes), if other objects do not change, then the unique object is determined as the missed object (step S406), and the script running is continued (step S422). In the context of the example shown in FIG. 7, with reference to 703, if a1 has only one unique child object a2′, and a2′ has the same class as the original a2 but has a different recognition property (e.g., name), then a2′ is determined as the missed object and performs relevant work of a2, and the script running is continued.

In one embodiment of the present invention, the method 400 further comprises: responsive to that among the one or more child objects there are a plurality of objects having the same class but different recognition properties as the missed object (step S404, No), specifying one or more properties of each object in turn as new recognition properties (step S408) until one or more possible target objects are recognized according to the new recognition properties. When a unique object is recognized (step S410, Yes), the unique object is determined as the missed object and caused to perform relevant work of the missed object before being missed, and the script running is continued (step S422). Since the missed object cannot be recognized according to the previous recognition property, the recognition property is changed, trying recognizing the missed object. Those skilled in the art should understand that the specifying one or more properties of each object in turn as new recognition properties may be implemented in various orders, including, without limitation, an order of high-to-low differentiation degrees of objects based on each property.

According to one embodiment of the present invention, the method 400 further comprises: when a plurality of objects are recognized according to the new recognition property (step S414, Yes), implementing the “perform the same action-compare” process formed by steps S304, S306, S312 and S314, is similar to the method 300 shown in FIG. 3; that is, causing all objects to perform the same action (step S416) so as to determine whether a following object fetched is the same as a following object that ought to be fetched from causing the missed object to perform the same action before change; determining an object leading to the same following object (step S418, Yes) as the missed object (step S420), and continuing the script running (step S422). According to one embodiment of the present invention, when there is no object leading to the same following object (step S418, No), relevant content of the following object is skipped over by commenting in the script (step S424). A following object fetched by the following object is used as a new following object fetched (step S426), and the step S416 is repeated tuntil an object leading to the same following object is found.

FIG. 5 shows a flowchart of a method 500 for automatically repairing a test script when determining that the change type of the object is class change, according to embodiments of the present invention. As shown in FIG. 5, responsive to determining that the change type of the missed object is class change (S210), one or more child objects of the parent object of the missed object are fetched (step S502); and responsive to that among the one or more child objects there is only one unique object having a different class from the missed object and the class is operable (step S504, Yes), if other objects do not change, the unique object is determined as the missed object (step S506) and caused to perform relevant work before no object is missed, and the script running is continued (step S522). In the context of the example shown in FIG. 7, with reference to 704, since in a1 there is only one object a2 having a different class (list) from the original a2 (whose class is table) and the class is operable, a2 is determined as the target object, and the script running is continued.

In one embodiment of the present invention, the method 500 further comprises: when among the one or more child objects there are a plurality of objects having different classes from the missed object and the plurality of objects are all operable (step S504, No), performing the following steps similar to steps S408-S422 of the method 400 as shown in FIG. 4: for example, specifying, in turn, each of one or more properties of each of the plurality of objects as a new recognition property (step S508) until one or more objects are recognized (step S510, Yes). Of course, those skilled in the art should understand that the specifying, in turn, each of one or more properties of each of the plurality of objects as a new recognition property may be implemented in various orders, including, without limitation, an order of high-to-low differentiation degrees of objects based on each property. Next, when an object is recognized uniquely (step S512, Yes), it is recognized as the missed object (step S514) and caused to perform relevant work before no object is missed, and the script running is continued (step S522). Moreover, responsive to that a plurality of objects are recognized (step S512, No), the flow proceeds to implementing the “perform the same action-compare” process formed by steps S304, S306, S312 and S314, similar to the method 300 shown in FIG. 3; that is, causing the plurality of objects to perform the same action (step S516) so as to determine whether a following object fetched is the same as a following object that ought to be fetched from causing the missed object to perform the same action before change (step S518); determining an object leading to the same following object as the missed object (step S520), and continuing the script running (step S522). According to one embodiment of the present invention, when there is no object leading to the same following object (step S518, No), relevant content of the following object in the script is skipped over unexecuted (step S524). A further following object fetched by the following object is used as a new following object to be fetched from causing the missed object to perform the same action (step S526), and the step S516 is repeated until the missed object is determined.

FIG. 6 illustrates a flowchart of a method 600 for automatically repairing a test script when determining that the change type of the object is hierarchy change, according to embodiments of the present invention. As shown in FIG. 6, responsive to determining that the change type of the missed object is hierarchy change (S204), one or more child objects (as described above, including direct child objects and indirect child objects) of the parent object (i.e., the first level of parent object of the missed object) of the missed object are fetched (step S602), and an object having the same class as the missed object is looked up in the one or more child objects. In hierarchy change, a typical circumstance is that the missed object is still under the same parent object but not in the original hierarchical structure, so a lookup is first performed among all objects under the same parent object. Upon lookup failure (step S604, No), one or more child objects of each level of the parent object are traversed upward along the new hierarchical structure. That is, first of all, respective child objects of the parent object (the second level of parent object of the missed object) of the parent object of the missed object are traversed, and then, respective child objects of the third level of parent object of the missed object are traversed, . . . , until the object having the same class is found (step S608, Yes) or the traverse fails (step S610, Yes). Still in the context of the example shown in FIG. 7, with reference to the change type 705 as hierarchy change, since a2 is not found among child objects of the original parent object (a1) of a2, the hierarchical structure is traversed upward to look up respective child objects of the second level parent object a0 of a2, at which point a2 is found among direct child objects of a0. The lookup process of 706 is similar to that of 705. That is, when a2 is not found among child objects of the original parent object (a1) of a2, the hierarchical structure is traversed upward to look up respective child objects of the second level of parent object a0 of a2, until a2 is found among the indirect child objects of a0.

In case of traverse failure, relevant content of the missed object in the script is skipped over unexecuted (step S612), while the execution of other content in the script is continued (step S622). This is because that if the missed object is still not found after traverse, then the greatest possibility is the missed object no longer exists. Hence, the execution of the script is continued by skipping over its relevant content unexecuted. As described above, a typical manner of skipping over is commenting out the relevant content of the object. When the one or more objects having the same class are found (step S608, Yes), the following process similar to steps S408-S422 of the method 400 with reference to FIG. 4 is implemented: with respect to one or more operable objects, specifying, in turn, as a new recognition property each of one or more properties of each of the one or more objects having the same class but different recognition properties as the missed object (step S614) until one or more objects are recognized (step S616, Yes); wherein responsive to that an object is recognized uniquely (step S618, Yes), it is recognized as the missed object (step S620) and caused to perform relevant work before no object is missed, and the script running is continued (step S622). Moreover, responsive to that a plurality of objects are recognized (step S618, No), the flow proceeds to implement a process similar to the “perform the same action-compare” process formed by steps S304, S306, S312 and S314 in the method 300 shown in FIG. 3, i.e., causing the one or more objects to perform the same action (step S624) so as to determine whether a following object fetched is the same as a following object that ought to be fetched from causing the missed object to perform the same action before change; determining an object leading to the same following object (step S626, Yes) as the missed object (step S628), and continuing the script running (step S622). According to one embodiment of the present invention, when there is no object leading to the same following object (step S626, No), relevant content of the following object in the script is skipped over unexecuted (step S630). A further following object fetched by executing the following object is used as a new following object to be fetched from causing the missed object to perform the same action (step S632), and the step S624 is repeated until the missed object is determined.

The methods 300-600 described above with reference to FIGS. 3-6 have described corresponding “self-healing” operations that are performed upon script running failure and determination of failure reasons so as to ensure the script will not be blocked at the failure but can continue to run subsequent steps. It should be noted that the respective “self-healing” operations will be recorded (for example, recorded in files) by the system without debugging, whereas the script will not be rewritten based thereon. In one embodiment, a user (e.g., tester) may write all recorded “self-healing” operations to the script one time and compile them together. In another embodiment, the user may for example choose a part of operations to rewrite the script or may not rewrite the script according to actual situations (such as the running situation of the script, the returned test result, etc.).
